Description
Technical field
The invention belongs to straw storing technology field, be specifically related to a kind of storage procedures of scale sweet sorghum stalk.
Background technology
Under the background that fossil energy and resource are petered out, the conversion of reproducible biomass resource and utilization are gradually by international, domestic concern.
Sugar grass (
sorghumbicolor(Moench) L.) be a kind of c4 specular removal crop of high-biomass, it has the features such as drought resisting, waterlogging, Salt And Alkali Tolerance, barren-resistant, wide adaptability.Current, China has an appointment the plantation of 450,000 hectares, produces sugar grass seed 220 ~ 2,500,000 tons per year, produces sweet sorghum stalk 2000 ~ 2,500 ten thousand tons per year.Containing the sugar of 16 ~ 22% in sweet sorghum stalk, containing the cellulose of 60 ~ 70% and hemicellulose in stem stalk, its processability is strong, purposes is precious extensively, from head to foot, and stem stalk produces wine and alcohol fuel; Residue after squeezing the juice can be used as the raw material manufacturing paper and fiber board, also can be used as the raw material of fuel ethanol production.
But due to sugar grass short for harvest time, after results, sweet sorghum stalk has high, the rich in sugar feature of moisture content, causes sugar loss in these stem stalks serious, causes the waste of resource; Stem stalk is perishable, and the degraded of the principal component such as cellulose, hemicellulose is fast serious, causes useful component damages serious, affects the production efficiency of material in post-production utilization; Most importantly, large-scale sweet sorghum stalk can go bad and degraded after receiving in a short time, the sweet sorghum stalk processing enterprise causing some large-scale cannot realize raw material supply all the year round, especially the 9-10 Ge Yuenei enterprise after sugar grass is received before 2-3 month to lower season harvest corn is without raw material supply, make enterprise normally cannot carry out production, can only close the door or use instead other raw materials, directly affect benefit and the development of enterprise.Ensure that supplying all the year round of sweet sorghum stalk is the important technology difficult problem that sugar grass resources processing utilizes.
At present, the storage procedures of maize straw mainly contains the buried technology of crushed material ensiling, crushed material climatic chamber anaerobism storing technology and whole stalk ventilated storage technology, adds preservative technology, cellar storage technology, technique of refrigeration, modified atmosphere storage technology etc., these methods extend the time of sweet sorghum stalk storage to a certain extent, but realize sweet sorghum stalk in the extensive storage not reducing useful component content as far as possible, also need science, feasible storing technology more.
In the technology of the sweet sorghum stalk microbial energy or biobased products, cellulose in raw material, hemicellulose can be converted into target product in theory, but because the lignin in raw material exists, significantly can affect the conversion ratio of raw material, destroy if given by the lignin component in raw material or degrade, the conversion ratio of raw material will obviously raise.
Summary of the invention
The object of the present invention is to provide a kind of storage procedures of scale sweet sorghum stalk.
The present invention is by the following technical solutions:
A kind of storage procedures of scale sweet sorghum stalk; sweet sorghum stalk is pulverized; the juice squeezed out in sweet sorghum stalk obtains sweet sorghum stalk slag; Phanerochaete chrysosporium spore suspension is added, then by sweet sorghum stalk slag stretched film environmental sealing, storage in room temperature in sweet sorghum stalk slag.
Sweet sorghum stalk slag per ton uses Phanerochaete chrysosporium spore 1-5kg.
The concentration of Phanerochaete chrysosporium spore suspension is 2 × 10
8-2 × 10
10individual/mL.
The water content of sweet sorghum stalk slag is 60-70%.
The preparation method of Phanerochaete chrysosporium spore suspension is: be forwarded on PDA medium by the Phanerochaete chrysosporium kind of 4 DEG C of preservations, after 37-39 DEG C of cultivation 7d, scraping Phanerochaete chrysosporium spore is in sterile water, concussion 30min forms Phanerochaete chrysosporium spore suspension, and spore concentration is 2 × 10
8-2 × 10
10individual/mL.
Phanerochaete chrysosporium is applied in the middle of sweet sorghum stalk storage by the present invention, because Phanerochaete chrysosporium a kind ofly can grow under aerobic conditions and can secrete the microorganism of certain Lignocellulolytic enzymes, also just say, in sweet sorghum stalk slag storage process, in earlier stage, utilize the oxygen packing middle retention, Phanerochaete chrysosporium strain can aerobic, have sugar condition under grow, and produce the enzyme that can make lignin degradation in sweet sorghum stalk slag, then make the environment of storage enter anaerobic condition; Later stage under anaerobic, can make other microorganisms not grow competitively, such that the sugar in sweet sorghum stalk slag, cellulose, hemicellulose do not reduce, not loss.Storage procedures of the present invention makes sweet sorghum stalk can keep storage of guaranteeing the quality in 6-8 month, but also by lignin component Partial digestion (15-30%) in long sweet sorghum stalk slag storage process, thus, can improve feedstock conversion is that the ability of later stage target product can increase 15-30%.Namely the inventive method can significantly improve the ability that sweet sorghum stalk biological transformation is bioenergy or biobased products.
Embodiment
Embodiment 1
The sweet sorghum stalk just gathered in the crops is pulverized, with squeezer, the juice in sweet sorghum stalk is squeezed out, obtain the sweet sorghum stalk slag that water content is 60wt%, in 1 ton of sweet sorghum stalk slag, add Phanerochaete chrysosporium spore suspension 18L(concentration 2 × 10
8individual/mL), then by sweet sorghum stalk slag stretched film environmental sealing, storage in room temperature.
Embodiment 2
The sweet sorghum stalk just gathered in the crops is pulverized, with squeezer, the juice in sweet sorghum stalk is squeezed out, obtain the sweet sorghum stalk slag that water content is 65wt%, in 1 ton of sweet sorghum stalk slag, add Phanerochaete chrysosporium spore suspension 18L(concentration 2 × 10
10individual/mL), then by sweet sorghum stalk slag stretched film environmental sealing, storage in room temperature.
Embodiment 3
The sweet sorghum stalk just gathered in the crops is pulverized, with squeezer, the juice in sweet sorghum stalk is squeezed out, obtain the sweet sorghum stalk slag that water content is 70wt%, in 1 ton of sweet sorghum stalk slag, add Phanerochaete chrysosporium spore suspension 18L(concentration 2 × 10
9individual/mL), then by sweet sorghum stalk slag stretched film environmental sealing, storage in room temperature.
Check experiment
The sweet sorghum stalk just gathered in the crops is pulverized, with squeezer, the juice in sweet sorghum stalk is squeezed out, obtain the sweet sorghum stalk slag that water content is 60-70wt%, then by sweet sorghum stalk slag stretched film environmental sealing, storage in room temperature.
Observe the situation of change of the sweet sorghum stalk slag of above embodiment, and the content of cellulose, hemicellulose, lignin during detection record certain hour, table specific as follows:
